REUBEN R. BARROW', OF MARL, ALABAMA.

WRENCH.

SPECIFICATION forming part of Letters Patent No. 586,473, dated July 13, 189

Application filed July-23,1896. Serial No. 600,214. (No model.)

To all whom it may concern:

Be it known that I, REUBEN R. BAnRow, a citizen of the United States, residing at Marl, in the county of Geneva and State of Alabama, have invented certain new and useful Improvements in Wrenches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in wrenches; and it has for its object, among others, to provide a simple and cheap construction of wrench composed of few parts, those readily assembled and most efficient in their operation. The holding device is mounted in a chamber or socket in the movable jaw. The fixed jaw is provided with a hole serving as a bur-set on belt-rivets and the concavity opposite thereto for braiding belt-rivets. The end of the shank is formed to constitute a screw-driver.

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be particularly pointed out in the appended claim.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which- Figure 1 is a central longitudinal section through my improved wrench. Fig. 2 is a transverse section through the movable jaw. Fig. 3 is a transverse section through the fixed jaw.

Like letters of reference indicate like parts in the several views.

Referring now to the details of the drawings by letter, A designates the shank, at one end of which is the fixed jaw, which may be of any suitable form, provided with an opening Z), serving as a bur-set on belt-rivets or other uses, and a concavity b for braiding belt-rivets or for other uses. The other end of the shank is formed to constitute a screwdriver O, and upon this end is ahandle D, of

any suitable form and material, beyond which the screw driver portion projects. The shank is screw-threaded upon one side, as seen at A.

E is a movable jaw sleeved upon the shank and having at one side teeth 6, adapted to engage those of the shank, while upon the opposite side this movable jaw is formed with a chamber or recess F, in which is pivotally mounted, as at g, the eccentric G, having a handle portion G, extending through the opening in the jaw.

The operation will be apparent. When the handle of the eccentric is thrown out or away from the shank, the eccentric is disengaged from the shank and the jaw free to be moved in either direction thereupon. When adjusted to its desired position, the handle of the eccentricis forced toward the shank, when the eccentric will engage the shank within the bore of the movable jaw and bind the latter securely in position. When the eccentric is disengaged from the shank, the movable jaw has sufficient play upon the shank laterally to disengage its teeth from those of the shank and permit ready movement of the movable jaw.

Modifications in details may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.

Having thus described the invention, what is claimed as new is- In a wrench 0f the character described, a
